Question

question 17
the hollow nasal cavity is separated by a midline partition called the:
septum.
conchae.
cribriform plate.
turbinates.
question 18
the fauces, one of the seven openings found in the pharynx, opens into the:
oropharynx.
nasopharynx.
esophagus.
both a and b are correct.
question 19
in the right lung, the superior and middle lobes are separated by the:
horizontal fissure.
oblique fissure.
bronchopulmonary segments.
hilum.

Explanation:

• Question 17: The nasal cavity is divided by a mid - line partition called the septum. Conchae (also known as turbinates) are structures that increase the surface area of the nasal cavity. The cribriform plate is a part of the ethmoid bone that forms the roof of the nasal cavity.
• Question 18: The fauces is the opening between the oral cavity and the oropharynx. The nasopharynx is located above the oropharynx, and the esophagus is a separate structure that is the passageway for food from the pharynx to the stomach.
• Question 19: In the right lung, the horizontal fissure separates the superior and middle lobes. The oblique fissure separates the inferior lobe from the superior (and middle in the right lung). Bronchopulmonary segments are functional units of the lung, and the hilum is the area where structures like bronchi, blood vessels, etc., enter/exit the lung.

Answer:

• Question 17: septum
• Question 18: oropharynx
• Question 19: horizontal fissure
